Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid! See both micro and macro pictures.

Our latest video highlights how to design student activity worksheets for in-class use of the PhET simulations. The simulations are created to guide students in inquiry-based exploration of scientific phenomena, and so are most effective when students use them in a hands-on setting. What questions can you ask students to help them achieve the learning goals that you have set for them, and to enable them to make their own discoveries? Watch this video for tips and recommendations from other teachers, and the PhET research team.
